Tốc Độ Giới Hạn is a unique app in Vietnam that helps you know the maximum speed limit of your current route. Designed to understand the difficulties and fatigue of driving in traffic, this app allows you to confidently control your vehicle anywhere, anytime*. One of its standout features is that it can operate without an internet connection**.

The app automatically updates the maximum allowed speed and your current vehicle speed, providing speed limit alerts to help you avoid unfortunate speed violations. This feature is especially useful in challenging weather conditions, such as rain, poor visibility at night, or when road signs are obstructed.

Another useful feature is the Trip Log, which automatically records your journey details, including distance, time, and maximum speed.

Key features of the app include automatic speed limit updates, speed limit alerts, voice alerts, a speedometer, trip logging, customizable settings, and offline functionality**.
